通过鼠标监听器更改Jbutton的图标

Question

I'm doing a board game project and I'm representing cells by Jbuttons. I made mouseLitener to all the buttons. My question is how to change the icon of the Jbutton when it is clicked ?

Answer 1

I'm doing a board game project and I'm representing cells by Jbuttons.

• use JToggleButton for game based on buttons array and mouse events, rather than JButton

• use ButtonModel instead of any XxxListener

• JButton and JToggleButton has implemented these methods in the API directly

.

setIcon(Icon i);
setRolloverIcon(Icon i);
setPressedIcon(Icon i);
setDisabledIcon(Icon i);

Answer 2

yourButton.addActionListener(new ActionListener() {
@Override
    public void actionPerformed(ActionEvent e) {
        yourButton.setIcon(new ImageIcon("yourImage"));
    }
});

ActionListener is called when you click on the JButton. This way is used most frequently.

作为替代，也可以考虑setText()使用Unicode字形，示出在这里 。
